Ro Water And Tds

Oh missed the ball valve part :blush:

Firstly DI goes on the good water pipe after the membrane so is the final stage.
Those ball valves, put them on every pipe exiting the membrane to lock the water into the membrane and stop it drying out!

Also on the unit after the membrane you should have a flow restrictor that matches your membrane: http://www.littleocean.co.uk/index.php?act=viewCat&catId=23 this should run next to another ball valve just like this:

the flow restrictor pushes water back to the membrane to use it better, the ball valve is so you can flush the membrane to make its life longer. You should do this for 10 mins ish before and after using it :D

Sorry for the essay! haha

Oh and a pic of you having 0 TDS :D

Oh Toby at little ocean has DI in stock: http://www.littleocean.co.uk/index.php?act=viewProd&productId=179
 
right ok i get it now.
so if you look at the pic for the ro unit i have in earlier post it has a flow restrictor on the waste one only it come s with that in place.
this right yes on just the one?
so ive got 2 outlets coming out of this so i have the waste strraight down drain
than the good one
connected to the di resin then do i just add a ball valve in a straight line.
and when not in use is it basically closed so it keeps membrane wet?
can i ask in your pic why is it before and after flow restrictor i assume thats what that is in pic mate?
does the di pod just connect straight to the tubing anything else needed?
also i want to ask the ro unit i have it is a
is it a 5micron or 1micron sediment filter for the ro unit above i wud need
also can you tell me from now how long till i should replace each of these stages incl di resin?
also howd do i determine how many gpd y ro is cos im not sure?
 
OK I hope I cover all of this :D

Ummm check the packaging on the membrane it should say what GPD it is, 50gpd or 75gpd etc? Its all in the membrane as to how much water is produced.

For replacing everything, firstly you should get 0 tds from after the DI, when that lowers, replace the DI as a first thing. Once that is exhausted I plan to replace it again but also replace the prefilters. The membrane is the last thing to replace due to it being the most expensive! Some people just change them every so many months but I think it depends on how you look after the unit.

With the micron Im not 100% sure but I don't think it matters as you have a compact unit, so you will have to buy the sealed pod with the filter in. Just buy the better one.

Sorry missed that there was a flow restrictor already there! OK with my picture the water comes from membrane from the top of the pic, you cant see it but there are arrows on the flow restrictor on mine. The reason it goes as in the pic, basically when the unit is running to make water the ball valve is shut,this causes water to go to the flow restrictor pushing it back to the membrane to get better usage. When you flush the unit to clear anything in there, you need to open the ball valve as it is in the pic, this means water just flows straight through the membrane to flush it all out. How that makes some sense?

So after the flow restrictor the water goes to the drain.

Yes you are right, the good pipe connects to the Di pod,you might need to cut a small piece of your pipe to do this.

With the ball valve put it before the DI pod to lock water in the membrane. Also put one before the flow restrictor and also one before the pipe running into the membrane.

When you are running the unit you run them all on open EXCEPT the one linking around your flow restrictor (my pic) that needs to be shut. Then when not in use close all the ball valves to lock in water.
The ballvalves will connect to pipe, so just cut the pipe where you want it and slide it in :D

Hope that helps?
 
yes thanks got it now.
is it just the waste outlet that has a flow restrictor on it?
as mine only has it on waste outlet
